stratovolcano
New Britain Island (Papua New Guinea), -5.33°S / 151.1°E 
Summit height: 1148 m / 3,766 ft
Current status: normal or dormant (1 out of 5)
Hargy volcano (also referred to as Eve, Galloseulo, Ibi, Richthofen, Gallosculo) is a little-known volcano in eastern New Britain, but it has one of New Britains's largest calderas, which measures 12 x 10 km.
There are no known historic eruptions and the last activity has been dated to ca. 1000 years ago, but weak fumarolic activity was observed from the SE side of the western summit crater during an overflight in early September 1990.
Numerous small eruptions have taken place from a vent inside the caldera (at the Galloseulo lava cone) over the past 7000 years.

Background
The Hargy caldera contains an inner caldera with a steep west-facing wall. The latest caldera-forming eruption of Hargy volcano took place about 11,000 years ago.The caldera floor is 150 m above sea level and contains a lake on the SW side, which drains through a gully in the northern rim.
A post caldera dacitic Galloseulo lava cone rises above and partially overtops the western rim of the caldera. A double crater occupies a larger 700-m-wide crater.

Remark:
Our list of volcanic eruptions closely follows the database of eruptions of the Smithsonian's Global Volcanism Project (GVP), the internationally most recognized data source for volcanic eruptions, but also includes significant eruptive episodes or related volcano events. "Volcanic eruptions" are usually to be understood as sequences of individual eruptive episodes that can follow each other, or even overlap (if several vents are involved), and can last many years, decades or even longer. For example, the current activity of Stromboli volcano is understood as a single eruption that has been ongoing since 1934.
